[mapguide-users] RE: Question about map.Create and map.Open() on the mapframe

[Chris Gountanis]

What we do in Coldfusion is set a session variable that can be accessed
server side anytime. That and the MapName is the only variables needed for a
successful viewer hack. The rest can be passed as URL query string. Sure the
concept is the same in JSP. Anyone know if there is a fprint equivalent in
Coldfusion so we can use the templates more effectively?

Hi Scott,
 
mapframe.jsp should only be called when a complete refresh of the page is
requested by the browser.  The page refresh was intended to get a new copy
of the map so the Create() call is appropriate.  If a user wants to refresh
just the map pane they can right click in the pane and hit refresh.  A
Refresh Icon can also be added to the WebLayout toolbar.
 
User sessions were not intended to go beyond the lifetime of the browser
session.  Certainly it is possible to do as you have found out with
modifying mapframe.jsp.  Just out of curiosity, how did you get around the
CreateSession() in mainframe.jsp?
 
Thanks,
Trevor

Subject: Question about map.Create and map.Open() on the mapframe


All,
I have a questions about loading a map from a saved MgSession.  I also think
there is a possible bug in the mapframe.jsp page that prevents the page from
loading a map saved in an open MgSession

In the mapframe.jsp the page always calls map.Create() forcing a new Map to
be drawn, even if the calling Session already has a Map object associated to
it with the same name.  Shouldn't the mapframe.jsp page do a check to see if
the map has been created to the calling MgSession and call a map.Open()
rather then a map.Create() so that the map will have the proper layers saved
in the users session?
 
I want to have the users map and dynamic layers persist throughout their
MgSession, but with the current code when the users accesses the main page
it always creates a new map (map.Create()), rather then doing a check and a
map.Open().   When I changed this code, the application performs as expected
and loads in the proper map for the users MgSession.  
 
Any help is much appreciated.
 
Thanks,
-scott
